Brass Plate
Overview
MEI rolls heavy-gauge brass plates from 6 mm to 80 mm thickness with sound internal structure and uniform hardness, suitable for machining, engraving, and structural applications. Because we cast our own bars, plates are free of the porosity and inclusions that plague material rolled from purchased scrap slabs — and every lot ships with chemical and mechanical test reports.
